Designed for workshop and jobsite use, it delivers 7.6 CFM at 40 PSI and 6.0 CFM at 90 PSI for inflation, fastening, spraying, and general compressed air tasks.

The KING INDUSTRIAL KC-2051H2 is built for users who need a portable shop air compressor with more output and durability than light-duty oil-free models. Its 2-cylinder cast iron single stage oil-lubricated pump is belt-driven for long service life, and the 20 gallon ASME registered tank supports a wide range of air-powered tasks. With a maximum pressure of 150 PSI, this unit is suited for inflation, blow-off work, light spray applications, and running many common pneumatic tools within its duty range.

This model is powered by a 5.5 peak HP motor and can be run on 120V or 240V single-phase power, with the unit pre-wired for 120V from the factory. The V-style pump design helps reduce vibration and improve cooling, while the regulator and easy-to-read gauges give the operator better control over outlet pressure. Large 10-inch pneumatic wheels and a front handle make it easier to move around a workshop, garage, service bay, or jobsite.
